Abstract
A deceleration sensor switch (10) comprises a base (12) and a mass (20) pivotable from an unactuated position to an actuated position when the mass is subjected to deceleration of at least a predetermined magnitude. A support (18) supports the mass (20) on the base (12) to pivot from the unactuated position to the actuated position. The support (18) comprises a single continuous piece of plastic molded material having one rigid end (97) portion fixedly attached to the base (12) and an opposite rigid end (99) portion to which the mass (20) is fixedly attached. The single continuous piece of plastic molded material has a resilient central portion (98). The central portion (98) acts as a hinge about which the mass (20) is pivotable from the unactuated position to the actuated position. The opposite rigid end portions (97, 99) are inflexible relative to the resilient central portion (98). First and second electrical terminals (30, 34) move into engagement with each other to electrically close the switch (10) upon the mass (20) pivoting from the unactuated position to the actuated position.
